Realization of a decarbonized area in Nagasaki City, combined with historical andtourism town development

With global warming and various extreme weather problems, carbon neutrality, an initiative toreduce greenhouse gas emissions to net zero, is becoming highly important.
In Japan, the ratio of renewable energy is not high among developed countries, due togeographical situations including the lack of plains in the country.

To achieve carbon neutrality in 2050, the government has selected advanced regional initiatives
as "Decarbonization Leading Areas" and has been promoting the "Decarbonization Domino effect"to spread these initiatives throughout the country and realize and accelerate decarbonization.

We have been working on a number of decarbonization projects in cooperation with local
stakeholders as well as the NTT Group.

In Nagasaki City, which is involved in this project, the local economy has stagnated due to thedecline of the fisheries and shipbuilding industries, and revitalization of the local economy is an
important issue.
We focused on Nagasaki City's abundant tourism resources and considered that we could solve
the problem by combining them with decarbonization efforts.

Therefore, we decided to promote Nagasaki City version of sustainable tourism that combines"historical culture," "night view tourism" and "decarbonization".
Through this initiative, we aim to both revitalize the local economy and decarbonize Nagasaki
City.

Nagasaki City and we are working together with the local community, the Tourist Convention
Association, and local university to realize local decarbonization and tourism promotion.

Our actions have been evaluated as a leading Decarbonization Domino effect program, and inNovember 2023, The Ministry of the Environment has adopted our project as one of theDecarbonization Leading Areas.

We are promoting three initiatives for regional revitalization and decarbonization.
The first is to provide our expertise for decarbonization.
We establish an energy management system for building facilities and implement energy-savingmeasures for historic buildings.
The second is to increase the value added of tourism.
We promote Nagasaki City version of Sustainable Tourism so that visitors can experience
historical culture in unison with citizens of Nagasaki City.
The third is to refine night view tourism.
We contribute to accelerate the nighttime economy by decarbonizing night lighting facilities.
We are responsible for formulating comprehensive strategies and supporting the promotion ofthese initiatives.

This initiative promotes the decarbonization of the cityʼs major tourist attractions, including
many World Cultural Heritage sites (the Oura Church, the former British Consulate, the former
Glover House), historic buildings and nightscape lighting overlooking Mt. Inasa, one of the worldʼs
new three best night views.
These areas face many restrictions on facility renovation to maintain the historic townscape.

Amid the restrictions, we are implementing thorough energy-saving improvements while taking
into consideration the landscape, supplying renewable energy to the city through local new powercompanies, and raising awareness of environmental issues for citizens and tourists withenvironmental education in collaboration with a local university and a MaaS application.

We estimate that these efforts will reduce CO2 emissions by approximately 60,000 tons, whichis equivalent to the amount absorbed by 200 hectares of forest.

We believe our expertise in decarbonization projects in areas such as Nagasaki, which have
many restrictions on facility renovation, should be extended to other areas of Nagasaki City, andfurthermore, to other projects in Japan that are facing the same problems.
We continue our contribution to realize Japan's goal of a " Decarbonization Domino effect ".
